TECHNICAL FIELD

[0001] The application relates to the technical field of sand and stone separating equipment, in particular to a sand and stone separating machine. BACKGROUND

[0002] With the rapid development of economic construction in China, a large amount of waste is generated in the construction industry. The traditional treatment method is mainly to dispose of the waste by landfill or open-air stacking, which not only occupies a large amount of land resources, but also easily causes environmental pollution. In recent years, the state policy guidance encourages the recycling of solid waste, which promotes the technological innovation and development of solid waste treatment equipment, especially sand and stone separating machines. The sand and stone separating machine is one of the important equipment for treating construction waste, and is widely used in the fields of sand and stone separation and concrete recycling. Usually, the sand and stone separating machine is placed outdoors, but in cold winter, the water contained in the sand and stone is easy to freeze, causing the sand or stone at the discharge port to freeze and bond, thereby blocking the discharge port. This phenomenon not only seriously affects the normal operation of the equipment, but also increases the maintenance cost and operation difficulty. Therefore, how to effectively prevent the sand and stone discharge port from freezing and blocking in a low-temperature environment has become a technical problem to be solved.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings, and the described embodiments are only possible technical implementations of the present application, and not all possible implementations. Those skilled in the art can obtain other embodiments by combining the embodiments of the present application without creative labor, and these embodiments are also within the protection scope of the present application.

[0021] The sand-stone separation machine provided by the embodiments of the present application comprises a rack 1, a separation cylinder 11 is rotationally connected in the rack 1, a sand discharge port 12 is arranged on the side wall of the rack 1, a stone discharge port 13 is arranged on the end of the rack 1, and a top-up mechanism 2 is arranged at the position of the sand discharge port 12 of the rack 1.

[0022] The top-up mechanism 2 comprises a positioning plate 21 arranged on the rack 1, a top-up plate 22 is slidably connected on the positioning plate 21, a plurality of top-up rods 23 are arranged on the bottom of the top-up plate 22, a guide rod 24 is fixedly connected on the top-up plate 22, a clamping plate is arranged on the side of the guide rod 24 away from the top-up plate 22, the guide rod 24 is slidably connected on the positioning plate 21, a return spring 25 is sleeved on the guide rod 24, one end of the return spring 25 is fixedly connected on the positioning plate 21, and the other end of the return spring 25 is fixedly connected on the clamping block 241. When the top-up rod 23 and the guide rod 24 move downward, the clamping block 241 compresses the return spring 25, the tension of the return spring 25 can drive the top-up plate 22 and the top-up rod 23 to move upward, so that the top-up rod 23 and the top-up plate 22 are prevented from falling due to the action of gravity, and the return spring 25 can drive the top-up plate 22 and the top-up rod 23 to move upward to reset. The selection of the return spring 25 can be adjusted according to the actual load condition, and generally, a spring with moderate elastic force is selected to ensure that the top-up plate 22 can quickly reset after each impact.

[0023] Specifically, the positioning plate 21 is fixed on the rack 1 for supporting and guiding the top plate 22. The top plate 22 can be made of metal material, such as stainless steel or aluminum alloy, which has good corrosion resistance and strength. The top rod 23 can be made of hard alloy or high hardness steel, which has good wear resistance and impact resistance. The length of the top rod 23 can be adjusted according to actual needs, generally 10-20 cm, and the diameter is 1-2 cm. The spacing of the top rod 23 can be adjusted according to the particle size of the sand and gravel, generally 2-5 cm, to ensure that the sand can be effectively impacted out of the sand outlet 12.

[0024] The bottom of the top rod 23 is provided with a notch groove 231, so that the end of the top rod 23 forms a sharp end 232. The design of the sharp end 232 makes it easier for the top rod 23 to insert into the frozen stones, thereby better separating the adhered stones. In addition, the sharp end 232 of the top rod 23 can also be designed as a cone or other shapes to adapt to different use scenarios. For example, for sand and gravel containing more fine particles, a conical sharp end 232 can be used; for sand and gravel containing larger particles, a flat head sharp end 232 can be used.

[0025] The side wall of the rack 1 is fixedly connected with a gas cylinder 26, the gas cylinder 26 is horizontally arranged, the piston rod end of the gas cylinder 26 is fixedly connected with a top plate 27, the side wall of the rack 1 is fixedly connected with two guide rails 28, the top plate 27 is clamped on the two guide rails 28 and can slide in the guide rails 28; when the gas cylinder 26 pushes the top plate 27 to slide, the guide rails 28 play a guiding and limiting role for the top plate 27, making the sliding of the top plate 27 more stable. The top plate 27 is provided with an inclined surface 271, the end of the guide rod 24 is fixedly connected with a clamping block 241, the clamping block 241 is clamped on the inclined surface 271 of the top plate 27 and can slide on the inclined surface 271. The piston rod of the gas cylinder 26 is elongated, pushing the top plate 27 to slide horizontally, the top plate 27 pushes the clamping block 241 to slide along the top plate 27, and in turn pushes the guide rod 24 to slide vertically, the top plate 27 pushes the top plate 22 to move vertically. The piston rod of the gas cylinder 26 can be extended or retracted, which can push the top rod 23 to move vertically and reciprocally to impact the frozen sand. The gas cylinder 26 can be selected as a high-pressure gas cylinder 26 or an electromagnetic gas cylinder 26 to meet the needs of different working conditions. The stroke of the piston rod of the gas cylinder 26 can be adjusted according to actual needs, generally 10-20 cm, to ensure that the top plate 22 can effectively move up and down.

[0026] The top plate 22 is provided with a baffle 29 close to one side of the rack 1, when the top plate 27 moves downward, the baffle 29 abuts against the inside of the rack 1, preventing the sand pushed by the top rod 23 from rolling back into the rack 1. The baffle 29 can be made of rubber or plastic material, which has good flexibility and wear resistance. The thickness and width of the baffle 29 can be adjusted according to actual needs, generally 2-5 mm, to ensure that it can effectively block the sand from entering the rack 1.

[0027] The baffle 29 is a telescopic plate, which follows the reciprocating sliding of the material pushing plate 22 downward, and can be telescoped to reduce the direct impact of the baffle 29 on the rack 1, and prolong the service life of the baffle 29. The telescopic plate design enables the baffle 29 to automatically expand when moving downward, and automatically contract when moving upward, thereby reducing the contact area of the baffle 29 with the rack 1 and the wear. The telescopic plate can be realized by a spring or an elastic material, or by a hydraulic or pneumatic device.

[0028] The baffle 29 includes a positioning sleeve 291 fixedly connected to the material pushing plate 22, and a material blocking plate 292 slidingly connected in the positioning sleeve 291, and a plurality of buffer springs 293 are arranged in the positioning sleeve 291, and the two ends of the buffer springs 293 are fixedly connected to the positioning sleeve 291 and the material blocking plate 292, respectively. When the baffle 29 is pressed downward, the material blocking plate 292 abuts against the rack 1, and the buffer springs 293 are compressed. The buffer springs 293 not only reduce the impact of the material blocking plate 292 on the rack 1, but also ensure that the material blocking plate 292 always abuts against the rack 1 by the pressure of the reset spring 25, thereby reducing the rolling of sand into the rack 1. The buffer springs 293 can be selected according to the actual load condition, and generally a spring with moderate elastic force is selected to ensure that the material blocking plate 292 can quickly reset after each impact.

[0029] The implementation principle of the embodiment is that the material pushing mechanism 2 is arranged at the sand outlet 12 of the sandstone separator, the material pushing plate 22 is driven to vertically reciprocate by the air cylinder 26, the material pushing rod 23 at the bottom of the material pushing plate 22 impacts the sandstone at the outlet to separate the sand that is bonded together, and prevent the sand from blocking the outlet. The sharp end portion 232 of the material pushing rod 23 is designed to make the material pushing rod 23 more easily inserted into the inside of the frozen stone, thereby better separating the bonded stones. The design of the reset spring 25 and the guide rail 28 enables the material pushing plate 22 to quickly reset after each impact, thereby ensuring the continuous work of the material pushing mechanism 2. The design of the baffle 29 effectively prevents the sand from rolling back into the rack 1, thereby improving the reliability and work efficiency of the equipment. Overall, the embodiment significantly improves the anti-freezing and blocking performance of the sandstone separator in cold weather through the optimized structural design, and improves the comprehensive performance and reliability of the equipment. The above are the preferred embodiments of the present application, but do not limit the protection scope of the present application, and therefore: any equivalent changes made according to the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
